山地城市景观生态风险与人类活动强度的空间关系分析
Analysis of the Spatial Relation of Landscape Ecological Risk and Human Activity Intensity in Mountainous Cities
摘要
Abstract
Under the interference of complex human activities,the change of landscape pattern of mountainous cities strongly affects the level of ecological risk.In order to reveal the spatial correlation between landscape ecological risk and human activity intensity in mountainous cities,Guiyang City was selected as a typical mountainous city,based on the remote sens-ing images and social economic data in 2000,2010 and 2020,the landscape ecological risk models and human activity in-tensity index were established,the spatial relation of landscape ecological risk and human activity intensity and their corre-lation were explored.The results showed that:from 2000 to 2020,the landscape ecological risk in Guiyang showed a down-ward trend,while the intensity of human activities showed an increasing trend,the variation amount of the landscape eco-logical risk in low-slope gradient was significantly higher than that in the other slope gradients,whereas the variation of the intensity of human activities in each slope gradient was relatively small.And the changes of landscape ecological risk and human activity intensity in the southern and central region were significantly different from those in the northern,western and eastern regions,there was a negative correlation between landscape ecological risk and human activity intensity,where-as there was obvious heterogeneity in different slope gradients.Controlling the human activities intensity of sloping land,in-creasing the implementation of ecological management projects,and improving the level of integrative and saving land use are the main directions of landscape management and human activities regulation in mountainous city in the future.This study can provide a reference for mountainous urban landscape management and human activities regulation.关键词
